HOT-AIR OR STEAM MOTOR.

SPECIFICATION forming part of Letters Patent No.340,824, dated April 27,1886.

Application filed October 2l, 1885.

.To LZZ whom t may concern,.-

Beit known that l, ARTHUR SGHMALZ, a citizen of the United States,residing at Dundee, in the county of Kane and State'of Illinois, haveinvented certain new and useful Improvements in Hot-Air and SteamMotors; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention relates to a hot-air or steam motor, and has for its objectto so construct the parts that a continuous How of water will beinjected into the air, so that the water will be constantly charged withair, in order to better and longer sustain animal and vegetable life,where the fountain is used either as an aquarium or for the growth ofplants.

To the accomplishment of the above and such other objects as the severalparts may be adapted to, the invention consists in the construction andthe combination of the several parts hereinafter particularly described,and then specified by the claims.

Figure l of the drawings is an elevation of the aquarium and motor; Fig.2, a side view, on airenlarged scale, of the motor, looking` at the pumpside thereof, with the pumpcyliuder in section and certain parts brokenaway. Fig. 3 is a plan view of the motor with parts broken away andothers in section. Fig. 4t is a front elevation of the motor with theseveral cylinders in section. Fig. 5 is a perspective of thepump-piston.

In the drawings, the letter A designates a stand of any approved design,on the top B of which is supported a glass or other transparent aquariumor water-vessel, C. Beneath this vessel, on a cross plate or bar, D,secured to the legs of the table, there is supported a table orstandard,E,at the upper end of which is a bed-plate, F. This bed-plate supportsthe lower head, G, of a liquid-reservoir, H, the head preferably beingformed with a flange, a, interiorly screw-threaded and eX- tending, asshown, through an opening in the bed-plate. The head may be secured tothe bed-plate by means of bolts b, and both the lower head and the upperhead, G', may be se- Scral No. 180,552. (No model.)

cured in any well-known way to the reservoircylinder H. \Vithin thereservoir-cylinder H there is a piston-cylinder, I, the lower part ofwhich is made separate from the upper part,and is held in place by ascrew-ange, a', engaging with the screw-ange a. The object of making thepiston-cylinder sectional is to permit access to the interior for anynecessary purpose, especially for the purpose of introducing water intothe lower part. The upper portion of the cylinder is secured rigidlywithin the reservoir in any suitable manner. A vent pipe or tube, J,leads from the cylinder to the outside of the reservoir for the escapeof air and vapor when heat is firstapplied to the cylinder, and itiscontrolled by a screw-plug, J

A hollow dis1 lacer,K,lits within the pistoncylinder, and it is formedwith a prolonged hollow neck or shank, K, preferably open at its upperend and extending up through the piston L, which has a tubular collar,ciitting around the neck of the displacer. This piston works within itscylinder I, and has the lower ends ot' the two connecting-rods M pivotedto it by bolts d or other suitable means. The upper ends of these rodsare connected in any suitable way to the crankshaft N, which issupported by brackets O, resting upon the top head, G', of the reservoirH. The crankshaft carries at opposite ends the ily-wheels P and P. Apin, e, projects from the wheel P', near the crank-shaft, and to its endthere is pivoted, by means ot' a screw, f, a link, Q, the other end ofwhich is pivoted by a screw, f', to the end of the crank-arm E, which issecured at its other end to the shaft S, journaled in the two arms g,which extend back from the brackets O. A pitinan, T, connected at oneend to the shaft S by a set-screw, h, is connected at the other end tothe shank ofthe dsplacer K by means of an elastic strap, U, secured tothe end of the pitman bynieans of ascrew, c', and to the shank or neck Kby means of a pin,j, the end of the strap preferably extending down intothe hollow shank. This elastic strap permits the pitman toV move in thearc ot' a circle without moving the displaeer out of a vertical line.

The wheel P has on its outside l'ace a plate IOC) or disk, 7i', to whichis secured a cap, la', by means of screws Z. The meeting faces of thedisk and cap are recessed so as to form a seat or socket for the ballm,which is connected by a rod, a, to the ball o, secured to the rod V ofthe pump-piston p. A ballandsockct joint connection or coupling is thusformed between the fly-wheel and pumppiston.

The pump-cylinder XV is supported by a bracket, q, resting upon thebed-plate F, and its head i' has the stuffing-box s formed with it.Around the upper portion of this box there is secured a cup, t, for whatlittle water may waste into it, and acap, u, screws onto the end of thestuffing-box.

The pump-piston p is flattened on opposite sides, p p2, between itsfaces or heads p p4, to form chambers p5 p between its sides and thesides of the pump-cylinder,while the fullsides p7 p8 constitute acut-off valve for controlling the flow of water into and out of the twochambers alternately. The upper face of the piston is provided withapertures c on one side of the piston, and the lower face with aperturesc on the opposite side, for the passage of water into the cylinderbetween thc heads of the latter and the heads of' the piston, so that alarger volume of water can be contained than in the chambers p5 and 1f'alone.

The pump-cylinder has an inlet, ai, on one side, which connects with thesource of sup- V ply through a pipe, Y, and an exit, w', on theopposite, which connects with the receivingvessel-in this case with thereservoir H- through a pipe, Y. These inlet and exit passages arecontrolled by the full sides pl and p8 of the valve-piston, so that whenthe piston is turned and at the same time moved in one direction by theball-and-socket coupling to the fly-wheel, the water is drawn into onechamber-say lil-while it is forced out ot chamber p, and then when thepiston has conipleted its stroke in that direction and been turned bythe ball-and-sockct coupling so as to bring the full sides of the pistonon the o pposite sides of the inlet and exit openings', and

the piston then reciprocatcd in the opposite' direction` the water willbe drawn into chamber 1f', and forced out of chamber p5, and thus thewater is alternately drawn into and forced out of the two chambers, anda continuous flow maintained.

In the drawings the pipe Y is shown as connected with the aquariumthrough a tube, Y2, provided with avalve, 102, and having ascreen, '103,to exclude rubbish and other foreign matter, and the pipe Y3,which leadsfrom the reservoir, connects with the rigid pipe y, passing up above theaquarium. The water drawn from theaquarium through pipe Y is forced bythe pump into reservoir H, and out thereof through pipes Y3 and Y4 intothe air above the aquarium, and after thus becoming charged with airfalls into the aquarium or vessel C, and furnishes pure or purifiedwater for the fishes or plants or other objects in the vessel.

To operate the motor a very small quantity of water is placed. in thelower section of cylinder I. A lamp or other heating medium is thenplaced under the cylinder I, and the vent-tube .I opened until the motoris fairly started,when it is closed. The heat from the lamp converts thewater into steam, which drives the piston L upward. This forces thedisplacer K downward,which forces the steam up into contact with thewater-cooled sides of the reservoir H, whereby the steam is reconvertedinto water, which falls to the bottom ofthe cylinder I, and there isagain converted into steam, when the action is repeated as at first. Ifthe water be not used, the parts will act as a hot-air motor, theexpansion of the air by the heat and its displacement by the displaeer,as in hotair motors, operating toactuate the pump and effect acontinuous flow of water.

This motor is very simple in the construction of all .its parts, and canbe made and run at the minimum of expense; and obvious changes in thedetails of construction of the several parts can be made withoutdeparting from the spirit of the invention.
